This bug (only on nokia s80 platform) related to the ChoiceGroup item , when a choiceGroup is appended to your form, none of your commands is visible anymore , except for exit and back commands.
A possible (and quite good ) solution is to add your commands to the choiceGroup itself, and implement the ItemCommandListener interface.
But what if you wanna add other items on the form , here where fun begins :) . The commands ( added to the choiceGroup) are only visible when the choiceGroup has the focus , and disappear once you select another item . A possible solution here is to implement the ItemStateListener interface , and in the itemStateChanged() method , you set the focus on the choiceGroup ( did not do it yet ) once an item is changed.
This will be a very bad behaviour of your application , the commands will keep appear/disapppear every time you change an item .
For my case , I'm gonna develop another version of the application for S80 particullary , this will require a totaly new UI design for some of my screens :(
